Abstract: ABSTRACT OF THE DISCLOSURE                A card file having a rotor with radiating arms, each of which has a card-carrying tray detachably connected there-to.  The rotor is mounted in a housing for rotation about a hori-zontal axis so that each tray can be brought to a detent-defined viewing position at which the tray is disposed in a substantially horizontal attitude affording ready access to the file cards carried thereby.  Inwardly facing ribs on the lower portion of the housing have their edges concentric to the axis of the rotor to be engagable by the outer extremities of the trays as they traverse the lower portion of their orbit upon rotation of the rotor, to thereby prevent detachment of the trays from the rotor arms. The various components of the rotor are held assembled with one another and with the housing entirely without reliance upon screws, bolts, rivets or the like.  Upon removal of the card trays from the rotor, they can be connected in side-by-side relation-ship by interengaging dovetails to form a rigid desk unit which facilitates reference to the contents of all of the trays.

Abstract: Abstract of the Disclosure An air flow velocity controller in a variable air volume control system interlocks a room temperature signal from a thermostat with the velocity set point so that the velocity controller maintains a constantly regulated amount of air into a room in proportion to the room's thermostat demands and independent of variations in the static pressure in the duct.           The controller includes a maximum lift cam and a movable spring fulcrum which are both mounted in a common cam housing to permit the maximum velocity setting to be adjusted for varying room requirements while main-taining a constant spring range regardless of the maximum velocity setting.    The controller is constructed to provide auto-matic compensation for control offset produced by changes in the static air pressure in the duct.           The controller includes the ability to control the air flow at a minimum velocity so that the air can be economically reheated or a minimum volume of air flow can be maintained for ventilation requirements.

Abstract: ABSTRACT OF THE DISCLOSURE  An induction motor of the squirrel-cage type is driven from polyphase power line through the inter-mediary of two cascaded thyristor arrays converting the line current into an adjustable rectified current and reconverting the latter into a stator current of variable frequency.  The magnitude of the rectified current is varied via the first thyristor array, under the control of a tachometric signal from a speed sensor coupled with the rotor of the machine, to maintain the rotor speed at a selected level within a predetermined dynamic range in which the stator current varies approximately in propor-tion to the slip frequency under changing load.  The slip frequency is adjusted by the second thyristor array under the control of an arithmetic unit which receives the tacho-metric signal along with a voltage feedback fromthe stator input and which maintains the stator voltage substantially proportional to rotor speed in order to stabilize the excitation current of the motor.  The maximum value of the tachometric signal fed to the arithmetic unit is limited by a clamping circuit to allow the selection of rotor speeds above the dynamic range without further increases in power.

Abstract: ABSTRACT OF THE DISCLOSURE           An exercising device having a housing which is attached to a stationary surface.  A cord with a hand grip on its free end can be pulled out of the housing against the internal resistance of the exercising device.  The amount of internal resistance can be varied by means of control  knobs.  An automatic rewind mechanism draws the cord back into the housing when the cord is released.  The device has, as a preferred specific feature, a manually adjustable resisting force mechanism.  This mechanism includes the preferred combination of a stationary capstan around which the cord is wrapped, and a variable force friction nip mechanism which (a) retards the cord-as it is pulled out of the housing, and (b) maximizes the capstan's frictional re-sistance by keeping the cord tightly wound around the capstan as the cord is being pulled out of the housing.

Abstract: A PROCESS FOR BONDING NONWOVEN WEBS     ABSTRACT OF THE DISCLOSURE     A process for bonding nonwoven webs of organic fibers having excellent textile-like softness, hand, and drape is disclosed. A web of uncompacted organic fibers is prepared, pressed between a pair of rolls, wherein one roll contains boss portions, a bonding solvent is transferred to the embossed roll, and at the roll nip, a limited quantity of solvent is applied to the web from the boss portions, and the web is simultaneously compressed in the areas under the boss portions, thereby forming a pattern of discrete bond sites. Compression reduces capillary spacing between the fibers which causes an increase in capillary retention of the limited solvent in the area under the boss portions. The rolls can be heated to enhance fiber fusion in the bond site, bond site uniformity, and removal of solvent.

Abstract: AN APPARATUS AND METHOD OF ASSISTING   PILE DRIVING BY ELECTRO-OSMOSIS                 Abstract of the Disclosure An apparatus and method of assisting the driving of a pile into soil containing water by electro-osmosis in which electrical direct current is directed through the soil for re-ducing friction between the pile and the soil allowing the pile to be more easily driven through the soil.  An electrically con-ductive base is connected to the bottom of the pile and an in-sulated electrical conductor is connected between the d-c power source and the conductive base.  A second electrical conductor is connected to the power source and terminates at a position spaced from but in electrical communication through the soil with the base whereby passage of electrical current between the base and the second electrical conductor reduces friction between the pile and the soil.  If the pile is electrically conductive, the conductive base is electrically insulated from the pile in order to direct current through the soil adjacent the base.  The second electrical conductor may be connected to the pile if the pile is conductive or in the soil or in water covering the soil.          After the pile has been driven, the electrical current may be directed through the soil adjacent the pile to dry the soil thereby increasing the load bearing strength of the soil.

Abstract: ABSTRACT OF THE DISCLOSURE     Parameters associated with a bus, which may be either an unshielded hollow conductor or a shielded hollow conductor, may be difficult to determine when the bus is carrying large currents at high voltages.  An indicator carrying a display is mounted internally to be visible through a window and thereby avoid conductors running from a high voltage region to an external place.  Thus tempera-ture of the bus can be determined within the hollow conduc-tor and can be used to activate a display adjacent an opening or window in the conductor.  The display may be powered by a power supply mounted within the hollow conduc-tor with the power supply deriving a voltage from longitu-dinally spaced points on the inner surface of the hollow conductor.  The current in the hollow conductor may be determined by measuring the IR drop between spaced points on the inner surface of the conductor, measuring the operating temperature of the conductor, determining the resistance from the measured temperature and the temperature/ resistance characteristic, and using the resistance and IR drop to determine current.  Similarly the IX drop can be determined by using a loop enclosing a longitudinally extending portion of the hollow conductor, and this in turn can be used to determine reactance if the current is known.

Abstract: ABSTRACT OF THE DISCLOSURE There is disclosed in a method for elimination of the chief impurities in aluminum dross. The method can be used as a pretreatment in the manufacture of aluminum sulfate from aluminum dross tailings in a continuous flow reaction zone in which the dross tailings prior to reaction with sulfuric acid are pretreated to reduce the more objection-able contaminants contained therein to acceptable levels.      The most objectionable contaminant in the dross tailings is aluminum metal which, in the invention, is oxidized with water or steam at elevated temperatures. The dross tailings, which are chiefly particles of aluminum oxide, are suspended in an aqueous slurry and the slurry is heated to a temper-sture from 185-225°F. and maintained under liquification pressures and sufficient agitation to onsure particle-to-particle attrition that removes an aluminum hydroxide coating which would otherwise inhibit the reaction. The reaction rate is accelerated by chemical and physical additives that can be optionally added to the slurry such as a trace quantities of caustic, which serves as a source of hydroxide ligands. to increase the solubility of aluminum hydroxide and/or refractory particles such as ceramic spheres which increase the attrition. Other contaminants present in the dross tailings include aluminum nitride, which is decomposed to aluminum oxide and ammonia, and aluminum carbide which is decomposed to aluminum oxide and methane. A continuous flow scheme for efficiently processing the oxides is disclosed.
